Features and Benefits:

– A stain around the weep hole is acceptable. However, if a weep occurs with the engine running and the coolant system pressurized, then the water pump should be replaced.
– After installation, pressure-test the system for leaks and check for sufficient fan blade clearance between the blade and radiator shroud.
– Clean all excess dirt and debris from the water pump housing.
– Clean all sealing surfaces, and make sure all old gasket material is removed before installing your replacement component.
– Clean and reinstall the coolant recovery reservoir before flushing the cooling system.
– Do not use any non-approved flush agents and replace the coolant according to manufacturer's specifications.
– Flush the cooling system completely, using power flush equipment or thermal cycling the system with clean water three times. The most effective method of system flushing is to use a coolant exchanger, following the manufacturer's operating instructions.
– Inspect for leakage at the water pump outlet housing or the rear cover gasket, and leakage at the water pump vent or weep hole.
– Inspect related components in the cooling system, including your fan blades, fan clutch, engine mounts, radiator, belts and hoses, and reservoir.
– Never strike the water pump shaft, since this will damage the new water pump.
– Run your vehicle to increase engine temperature, and ensure the system is pressurized.
– Torque all bolts according to the manufacturer's specifications and adjust belts to proper tension (if applicable) to manufacturer's specifications.
– Use sealant tabs only if recommended. Some sealant tabs or similar compounds may restrict coolant flow through the passages of some cooling systems.
– With the new pump installed, turn the hub by hand and check for rotation.
Before purchasing and installing an engine water pump, make sure it is the correct fit for your vehicle.
